Dependence of Microstructure Evolution and Mechanical Properties on Loading Direction for AZ31 Magnesium Alloy Sheet with Non-basal Texture During In-Plane Uniaxial Tension

In-plane uniaxial tension of AZ31 magnesium alloy sheet with non-basal texture has been conducted in order to demonstrate the effects loading direction on microstructure evolution and mechanical properties at ambient temperature. Loading axes are chosen be along five directions distributed between rolling (RD) transverse (TD), allowing various activities involved slip twinning modes take place. As for modes, electron backscattered diffraction observations confirm that contribution $${{\{ 10\overline{1}1\} }}$$ compression is minimal plastic deformation all deformed samples. By comparison, 10\overline{1}2\} extension (ET) not only serves as an important carrier sustaining accommodating strain but also contributes emergence TD-component progression strain. In terms analysis Schmid factor demonstrates increasing tilted angle RD unfavorable activation basal slip, whereas it prismatic slip. These consequently explain tendency 0.2% proof yield stress. Moreover, activations ET collectively contribute concentration two poles toward normal direction. With RD, gradually weakened. This leads a weakening about poles, generally Lankford value (r-value) decreasing strain-hardening exponent (n-value).
